the study of thermal energy

In a transfer of heat, the item that is hotter is the heat source, and then there is an item that receives the heat called this.

This is not a good insulator.

heat energy

Heat flows from the hotter things to the colder things, resulting in thermal equilibrium

Conductions occurs when a heat source and a heat sink are connected through this.

A campfire, an iron, and a toaster all have this in common.

a chemical process in which some material reacts quickly with oxygen to give off heat

The entropy of something approaches its minimum as it is cooled toward absolute zero

This scale measures water freezing at 32 degrees.

These elements must be present to keep a fire burning.

a measure of disorder

The universe as a whole is becoming less and less ordered or organized.

This scale measures water freezing at 0 degrees.

This is the one substance that expands when it freezes.

heat that transfers in fluids; liquids and gases

Energy and matter can never be created or destroyed.

This scale measures water freezing at 273.15 degrees.

Radiant heat is transferred through this.
